Configuration
Status N/A variable length Query only.
Used to Query the Configuration status of the unit N/A RCS? RCS=x….x
(See Description of
Arguments)
Example: Description:
<1/RCS?’cr’
>0001/RCS=’cr’
ESW=1’cr’
AFR=1’cr’
XRF=N/A’cr’’lf’
Redundancy Mode
Auto Fault Recovery
XRF = External reference status, N/A = no external reference, 05M
for 5 MHz, and 10M for a 10 MHz
Note: XRF will always be N/A if the internal reference oscillator
option is not installed.
Reference
Oscillator
Tuning REF= 3 bytes Command or Query.
Adjusts the reference oscillator tuning voltage by sending a DAC
value in the following format: REF=xxx, where xxx is a numeric
value from 0 to 255.
Default value: 087
Example: <1/REF=087’cr’
>0001/REF=’cr’’lf’
Note: This command sets the DAC value, but the actual Reference
Oscillator tuning voltage can be monitored using the RMS
command.
REF=
REF?
REF* REF? REF=xxx
(Same format as command
arguments)

Maintenance
Status N/A variable length Query only.
Used to Query the Maintenance status of the unit. N/A RMS? RMS=x….x
